Help with cleats

Need help with finding football cleats. In especially pumas I find it hard to know exactly what version of the shoe it is. For example I am watching videos on good shoes and someone recommended puma king ultimate 2.0. But I can only find king ultimate. Now they look the exact same so I am pretty sure they are the right ones but not 100%. Plus this has been confusing in other cases as well. So my question is if there might be something I’m missing or have misunderstood?
